Your systems should pass data to each other automatically, not wait on someone to copy and paste.
Custom integrations that connect your CRM, ERP, payment, and marketing tools so records stay consistent and work moves without manual re-entry. Built by the same team that runs your growth and engineering, so nothing gets lost in a hand-off.
Integrations Development connects the tools your business already runs so data flows between them without manual re-entry, exports, or copy-and-paste reconciliation. We build clean, documented APIs, third-party connections, and event-driven workflows that keep your CRM, ERP, marketing platform, payment processor, and accounting system in sync. The result is fewer silos, fewer errors, and hours of ops time given back every week.
The difference is where this work sits. At Rule27, integrations are built inside the same engineering studio that ships your product and the same growth team that runs your pipeline, so the person wiring your CRM to your marketing automation understands what the marketing team actually needs from that data. Four studios, one roof, zero hand-offs. That means no vendor coordination, no finger-pointing when a sync breaks, and no lost context between the team that scoped it and the team that built it. Where simple, no-code tools genuinely fit a workflow, we use them. Where a connection is high-volume or business-critical, we build custom code that gives you real error handling, real control, and no per-task pricing surprises.
This service is for operations, RevOps, and technical leaders who are done exporting spreadsheets to keep two systems agreeing. Every integration ships fully documented, deployable independently of our team, and owned outright by you. Technical and ops engagements reference a $175/hr technical-buyer model, and larger builds are scoped as fixed-price projects so you know the number before we start.
Built to deliver.
REST and GraphQL API development, clean, documented, and versioned so your systems connect reliably and stay maintainable

Analysis
We map the systems, the data that needs to move between them, and the exact triggers and rules that govern each flow. You get a precise scope before any code is written.
Architecture
We design the integration end to end, choosing custom code or a no-code tool per workflow based on volume and how business-critical it is, then define the error handling and monitoring up front.
Development
We build the APIs, connections, and workflows with versioning, retry logic, and logging in place, and document everything as we go so the code is yours to run.
Testing and Deployment
We validate every flow against real data and edge cases, wire up the monitoring dashboard and alerts, then deploy to production with the 90-day warranty active.

Asked often.
What systems can you integrate?
Any system with an API. Common builds include CRM connected to marketing automation, ERP connected to e-commerce, payment processors connected to accounting, and custom webhook flows between any tools in your stack. If a platform exposes an API or webhooks, we can connect it.
Do you use Zapier or similar no-code tools?
For simple, low-volume workflows, yes, when it is genuinely the right tool for the job. For complex, high-volume, or business-critical integrations, we build custom code that gives you better error handling, more control, and no per-task pricing surprises as your volume grows. We recommend the approach that fits the workflow, not the one that locks you in.
How do you handle errors when an integration fails?
Every integration ships with error logging, alerting, and retry logic, so transient failures recover on their own and you are notified immediately when something needs attention. You also get an admin dashboard to monitor status across all your connected systems in one place.
What happens if one of the platforms changes their API?
Breaking API changes are covered under a maintenance retainer. We monitor your integrations and push updates when a platform ships a change that would otherwise break the connection, so you are not the one who discovers it when the data stops flowing.
Do I own the integration code?
Yes, one hundred percent. All code is yours, fully documented, and deployable independently of our team. You are never locked into keeping us on to keep your integrations running.
How long does a typical integration take, and what does it cost?
Simple two-system integrations run one to two weeks; multi-system workflows with complex logic run three to six weeks. Projects are scoped as fixed-price builds (simple integrations start around $5,000, complex builds around $15,000, enterprise orchestration at $30,000 and up), with ongoing technical and ops work referenced at $175/hr. We scope precisely during discovery so the number is set before we start.
